Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66436, here are decompositions:

5 + 66431 = 66436
23 + 66413 = 66436
53 + 66383 = 66436
59 + 66377 = 66436
89 + 66347 = 66436
197 + 66239 = 66436
257 + 66179 = 66436
263 + 66173 = 66436

Showing the first eight; more decompositions exist.
